We present a closed form solution to the nonrigid shape and motion (NRSM) problem from point correspondences in multiple perspective uncalibrated views. Under the assumption that the nonrigid object deforms as a linear combination of K rigid shapes, we show that the NRSM problem can be viewed as a reconstruction problem from multiple projections from ℙ3K to ℙ2. Therefore, one can linearly solve for the projection matrices by factorizing a multifocal tensor. However, this projective...[Show more]
